_The Knowledge of Art and Science._--The Hindoos from a remote antiquity cherished the knowledge of the heavenly bodies, reckoned eclipses, and watched the motion of the stars. These they did and do by means of their fixed system of astronomy; they have no scientific apparatus at all. European astronomers calculate the day of the eclipse, using several instruments, but the Brahmuns do the same thing without such aid. Architecture was known to them also from a distant period. The remains of the old temples and ghauts in various parts of India distinctly speak of their proficiency in architecture. On the temple walls you will see the representation of the heavenly bodies, the signs of the Zodiac, and the images of their gods, carved by men who had lived, so to speak, in the very infancy of the world. The knowledge of minerals was found among them also, for the universal use of gold and silver ornaments, and metallic household utensils, is evidence of the fact. They are unrivalled in the skill of working in gold and precious stones. The manufacture of fine cotton cloth, such as Dacai, and of shawls (the Cashmere), has obtained the undisputed applause of the world. In fact, the Hindoos did and do largely cultivate all the appliances of civilized life. Only their knowledge of art, science, and civilization is not progressive, but limited. They feel satisfied to live, move, and die within the boundaries of their own acquirements, and hardly desire to add to or vary from the prescribed institutions of their forefathers. While the countries beyond Hindostan are making astonishing advances towards enlightenment, discovering new inventions for promoting temporal comforts, and introducing the best and choicest things of the world among themselves, the Hindoos dig trenches round their borders, and nourish their old national institutions in good earnest. But there is a strong possibility that a mighty revolution will take place in the social and spiritual condition of the country. The introduction of European civilization has dazzled the eyes of the young, some of whom, (though few,) are now eagerly co-operating with their friends for the welfare of the country. The School of Industrial Art, the Civil Engraving College, the Medical College, etc., are blessings coming from the British Government, and to these the young men from the high classes resort for instruction and improvement. The Hindoos possess remarkable genius in imitating almost everything put before them, provided their caste and religion do not interfere. The low-caste people who work in the English factories, warehouses, steamboats, etc., display a ready and admirable talent for the business. On the Ganges, the uneducated, low castes manage steamboats. They serve in various capacities in the dockyards, founderies, factories, etc. * * * * *
